A TTORNEYS.

Patented Jan. 21, 1941 UNITED STATES sroor. on REEL Robert V. Olson, At'tleboro, Mass., assignor to Mossberg Pressed Steel Corporation, a corporation of Massachusetts Application June '1, 1939, Serial No. 27 1,15;

. 10 Claims.

This invention relates to a steel spool or reel of a character usually utilized for the packaging of metal wire such, for instance, as copper wire, which may be wound thereon for various purposes such, ior instance, as for annealing after drawing to a difierent size.

One of the objects of this invention is to provide a means to prevent the line wire which may be packaged on the spool from entering a crevice 10 which may be formed between the head and the barrel of the spool, to thereby prevent injury to the spool and to the wire wound thereon.

A more specific object of the invention is to provide means between the riveting connecting of 15 the barrel and head along the portion of the spool between such riveting connection where the crevices sometimes "appear, to provide a bridging projection at this location where a crevice may appear to span the crevice and prevent the entry 20 of a wire between the end or edge of the barrel and the head.

Another object of the invention is to strengthen the connection of the head to the barrel around. the peripherial extent of the barrel where it 25 abuts the head, and to at the same time prevent entry of the wire into a crevice which might be formed between the barrel and the head at the location between the riveting connection of these two parts together.

invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the construction of steel spools the barrel end abuts the head and is secured thereto at spaced intervals such, for instance, as by the riv- With these and other objects in view, the" eting over of portions of the barrel extending thru the head, it frequently occurs when stresses occur in the wire wound on the spool that the strain present in the spool will cause a flaring of the head, in which case a small crevice may occur 5 at the juncture between the head and the barrel between the portions forming rivets oi the barrel so that a wire may crowd down into such crevice, and damage the wire and the spool, and in order to overcome this diiiiculty I have pro- 10 vided an arrangement to bridge the space between the head and the barrel at theselocatiom between the rivet lugs by shearing out and bending a portion of the head to provide a projection extending inwardly of the spool, and I provide a recess corresponding in shape to the shape of the projection so that the edges of the projection and the edges of the recess will substantially abut, thus any crevice which may be formed is bridged by such projection and in instances where I secure the edges of the projection to the edges of the recess, the connection between the head and the barrel is strengthened, and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished. a With reference to the drawing, l0 designates a barrel formed cylindrical in shape, usually from sheet stock, with its abutting edges suitably secured in some cases such as by welding. II denotes a head which is secured to the end of the barrel; two such heads serve to provide flanges between which heads or flanges the wire is packaged to maintain it in position as it is wound.

In order to secure these heads at the opposite ends of the barrel, I have provided lugs i2 at spaced locations about the endsof the barrel and slots l3 similarly spaced thru the heads'so that the projection l2 may extend thru these slots I3 40 and there be headed over or riveted or welded as at [4, so as to hold the heads in. position at the' ends of the barrel. Such formation is quite customary in the trade.

It frequently occurs that a flaring of the head caused by stress against the head beyond the elastic limit of the material will cause a crevice to be formed between the barrel and the head at locations between thelugs I2 so that a wire may become forced in between the head and the barrel in such crevice, thereby accentuating this condition, and in order to prevent wire from entering a crevice so formed and at the same time strengthen the connection of the heads to the barrel so as to reduce to a minimum the possibility of such crevices being formed, I cut out recesses I5 in the edge of the barrel and I shear or cut and bend up projections l6 from the sheet metal stock of the head and so shape these out and sheared up projections I6 that they will closely fit into the recesses IS in the barrel and I so form these projections l6 that they will be arcuate on their outer surface to providea surface which will be substantially flush with and conformed to the cylindrical surface of the barrel, and in order that these projections may be maintained in position, I weld, brace or solder the edges of the projection to the edges of the recess as at I1 in Fig. 2 such, for instance, as by spot welding, which serves to hold these projections in position and also to strengthen the connection of the head to the barrel.

The projections which I have just mentioned designated It in Fig. 3 and the recesses I5 in the barrel are of corresponding shape but the particular shape of the projections and the recesses may vary, I having illustratedin Fig. 8 a projection of a regular rectangular formation designated l8, while in Fig. 9 I have shown one which is frusto-triangular H), or the same may be triangular as illustrated in Fig. 10 at 20, various selected shapings being a matter of mechanical expedience within the choice of the manufacturer.

In some cases a stronger reel may be desired and I have illustrated in Fig. '7 a reinforcing plate 2| provided on the outer surface of the head Ila with the projection I2 (in this case somewhat longer) extending not only thru the flange reel may be further strengthened by the provision of a band 23 located within the barrel and abutting the inner surface of the head Ill, also abutting or contacting the inner surface of the barrel i0 and being of a length to extend beyond the recesses in the barrel and providing a bottom wall therefor, thus forming pockets for the projections. This band is secured in-place by having its end welded, :bra-zed, soldered or rivetted to the head or its outer surface welded,

brazed, soldered or otherwise suitably secured to the barrel. In the instant case, this band 23 is secured to the head by welding as at 30 and to the barrel by welding as at 3|. These bridging projections l6, l8, l9 or 20 are welded, brazed or soldered to it and these projections likewise can be welded to the edges of the recesses into which they project. As shown in Fig. 7, the projection I6 is secured to the edge of the recess and to the band 23 by welding as at 32. v

Other strengthening construction of the reel or spool which may be utilized, is that of rolling the edge of the head as at 25 and providing a center tube 26 which extends centrally thru the barrel and thru openings 2-! in the head, the peripheral edges 28 of which are strengthened by the deflecting of the stock while the center tube 26 is flared outwardly as at 29 over the surface of the strengthened portion 28 about the opening 21 to assist in holding the head on the end of the barrel and generally reinforcing the entire reel or spool, while at the same time providing a long bearing for the rotation of the spool on its axis.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the apabutting portions of the end of the barrel,
